.lMPROVEMENT IN MACHINES FOR MAKING HEADS OF WOODEN BOXES.

I Specification forming part of Letters Patent N 0. 169,700, datedNovember 9, 1875; application filed September 22, 1e74.

To all whom it may concern:

Be it known that I, EDMUND HERSEY, of Hingham, in the county of Plymouthand State of Massachusetts, have invented certain new and usefulImprovements in Machines for ()utting Wooden Heads and Bottoms forBoxes, and for other articles, of which the following, taken inconnection with the accompanying drawings, is a specification:

My invention relates to a machine for cut ting the bottomsand heads ofwooden boxes, the bottoms of wooden 1')ails,-barrel-heads, and variousarticles too numerous to mention here; and itis an improvement uponthemachine patented to me March 12, 1867, and

.M y invention relates, more especially, to the arrangement of thecutters, and to the means employed to operate the reciprocating plungersand control their action; and it consists, first, in securing saidplungers to the opposite ends of a toothed rack, fitted to slide in asuitable bearing formed for the purpose in a stand, bolted or otherwisesecured to the frame,in the center of its length, and suitable gearingto impart to said rack a reciprocating motion, anda'shipper-lever,acting upon a clutch or sliding gears, for the purposeof re-, said rack and plungers.

toothed rack and plungers a shipper rod or bar, arranged to be movedendwise in either direction by saidplungers, and provided with pins orshoulders upon either side of the shipper-handle, as a means ofautomatically moving said shipperhandle, to disengage the gearing andstop. the motion of the plungers. It further consists in theuse uponsaid shipperbar of a pointed pin or lug projecting downward therefrom,in combinationwith a stationary double incline, over which said pointtravels at each motion of said bar, and thereby raises theshipper-handle, and disengages it from the lockingdevice. My inventionfurther consists in the use of a safety-guard, placed slightly in frontof the extreme point of the cutting-edge of the knife, to prevent theoperator from getting his hands against the cutters.

In the drawings, Figure 1 is a plan view of my improved machine. Fig.

2 is a longitudiq nal section on line or ac. Fig. 3 is a transversesection on lineg 3 on Fig. 1. Fig. 4 is a transverse section on line z2' on Fig. 1, and Fig. 5 is a detail illustrating the shipping device.

A A is the frame of the machine, and B B are two knives or cutters, madein the form of hollow tubes, and held in fixed positions at oppositeends of the frame A, to which they are secured by the clamps B Saidcutters may be cylindrical, oval, or of other desirable form incross-section, and have their front or cutting ends ground to a circularor oval shape, (see Fig'. 1,) with an exterior bevel, so that thecutting-tube is considerably shorter on the two sides than upon the topor bottom, so that when a blank is presented to the cutter, the cutterwill first strike the blank at the top and bottom, and, as the blank isfed along the cutter will cut away the surplus wood, by a drawing cut,in four dili'erent directions, in the same manner as in the case of themachine patented to me, as before referred' to. O O are two guide-boxesor chutes, into which a pile of blanks or square pieces of boards, ofsuitable thickness to make box bottoms or covers, may be placed, eachblank resting upon its edge on the bottom of the chute O or C,with thegrain of the wood in' a horizontal direction, and at right angles to theline of motion of the plungers. D is a toothed rack fitted to moveendwise in a dovetailedbearing formed in the stand E, secured totheframe A in the center of its length. and

D and D are blocks of wood, secured one to each end of the rack D, andserve as plungers to force thepile of blanks through the cutters. F is apinion mounted on the middle of the shaft G, in position to engage withthe rack D, said shaft G being mounted in the bearings H H, and havingsecured to its other end the large spur-gear wheel I, which engages withand is driven by the pinion J, secured upon the end of the shaft K,which also has secured thereon the two bevel-gear wheels L and L, and isso mounted in the bearings M M that it is free to revolve therein, andat the same time it may be moved endwise therein.

N is the main drivin g-shaft, mounted in the bearings N N,

with its axis at right angles to -the shaft K,'and having securedthereonthe driving-pulley O and the'bev'el-gear wheel formed therein'for thepurpose. R is a shipper rod or. bar, fitted to suitable bearingsdirectly under,'and parallel to, the toothed rack "D, and provided withthe pins 0 and c, andd and d, projecting upward therefromfas seen inFig. 2. The pins 0 and c are placed one upon either side of the handleor long arm of the shipper-lever Q, and by contact therewith, when thebar It is moved endwise, said shipper-handle is moved in the samedirection the bar is being moved, and thereby disen= gaging the gears Lor L from the gear P, and stopping the motion of the plungers D and DThe pins cl and 01 extend upward so far thattheir upper ends aredirectly in the path of the plungers D and D, which, respectively,

strike said pins d and d alternately just be fore-they reach the extremeof their back- -ward:stroke, and thus cause the bar B to move endwiseuntil one of the pins 0 or c strikes the 'shipperhandle, as abovedescribed.

.beveled or pointed lug, e, projecting down- The'bar It is also providedwith a ward fromits under side about equidistant from the pins 0' and c,which comes in con- I tact with, and rises over, the double-inclinedsurface of the girt f, which causes the end of the bar It, and throughit the shipper-handle Q, to be raised sufficiently to disengage saidshipper-handle from the'holding-catch g before-the pin 0 or 0' comes incontact .therewith to move it forward.

The operation of my improved machine is as follows: Suppose the rack Dand the plunx gers D and 1) to be at the extreme end of their motion tothe right, when the guide-box .0 will be clear, and may be filled withblanks, set on edge, say to the number-of fifty, more or less. Now, ifthe shipper-handle be moved into the position shown in the drawings,where it is held by the catch g, the bevel-gear L will be engaged .withthe gear P, and the rack D ,Willbe moved endwise, carrying the plunger Dtoward the left-hand end of the machine,

and forcing the pile of blanks, previously placed in the .guide-box O,toward and against the cutting-edge of the tubular knife B, whichvcutsaway the surplus wood, reducing each blank in succession to auniform symmetrical shape, exactly conforming to the interior shape ofthe knife, through which they are forced and delivered from its outerend. This motion ,continues until the plunger 1) strikes the pin d, andmoves the shIpper-barR endwise until the pointedlug 0, moving up theinclined surface'ofthe girt f. raises the shipper-handleQ fromthecatchg, and the pine comes in contact with said shipper-handle andmoves it far enough to disengage the I gears P and L, when the motion ofthe machine will cease. with the plunger D in a position to admit of theguide-box G being filled with blanks. This being done, theshipper-handle Q is moved by hand to the left, so as to engage the gearsL and P, where said lever is held by the opposite end of the catch y,when the machinery is again set in motion to move the rack D and itsplunger D from the left to the right, forcing'the pile of blanks throughthe cutting-tube B and delivering them at its outer end, said motioncontinuing until the plunger D strikes the pin d and moves theshipper-bar R endwise in the same direct-ion that the plunger is moving,until the pointed lug e is moved up the other inclined surface of thegirt f, raising the end of the bar R and the shipper-handle Q, anddisengaging it from the catch g, when the pin 0 will strike theshipper-handle and move it tothe right until the gears L and P aredisengaged, when the motion of the mechanism will cease.

S and S are guards to prevent accident by the operators ha-ud coming incontact with the knife.

Instead of the guide-boxes G and 0', plain tables may be used with agage-bar, said table answering to the bottom of said boxes, and the gagebar answering to the back upright side of said box.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is-

1. The combination and arrangement of the knives B and B, the toothedrack I), having secured to its opposite ends the plungers D andv D andthe pinion F, arranged to be intermittently rotated in oppositedirections, and thereby impart a reciprocating motion to the rackl) andplungers' D and D as and for the purposes described.

2. The combination of the knives B and B formed as set forth, theplungers D and D rack D, pinion F, gear I, pinion J, sliding shaft K,bevel-wheels L, L, and P, and shipper-lever Q, all arranged to operatesubstantially as described.

3. The combination of the reciprocating plung'ers'D and D, theshipper-lever Q, catch g, the shipper-bar It, provided with the pins 0,0, cl, and d, and the pointed lug e, and the double-inclined uppersurface of the girtf. arranged to operate substantially as described.

4. In combination with the knives B and B one or both, the safety-guardsS or S, arranged substantially as described, for the purposes specified.
